LteX2Manager

simple module

Serves as a pluggable interface for submodules of the e/gNodeB's LTE/NR protocol stack that implement functionalities requiring the use of the X2 interface for communication with peer e/gNodeBs, such as handover, dual connectivity, and Coordinated MultiPoint (CoMP). Simplifies the interaction for such submodules by abstracting the details of X2Apps, which are the modules responsible for the actual communication through the X2 interface.

Used in compound modules

Name	Type	Description
LteNicEnb	compound module	The LteNicEnb module is a network interface that provides LTE connectivity within an eNodeB. It implements the data and signaling planes of the LTE stack, which includes the PDCP, RLC, MAC, and PHY layers. The parameters and submodules allow customization of the eNodeB's behavior, including whether it supports D2D communication, CoMP (Coordinated MultiPoint), or dual connectivity.

Parameters

Name	Type	Default value	Description
interfaceTableModule	string
binderModule	string	"binder"

Properties

Name	Value	Description
display	i=block/cogwheel

Gates

Name	Direction	Description
dataPortIn [ ]	input	Incoming connections from X2 user modules
dataPortOut [ ]	output	Outgoing connections to X2 user modules
x2In [ ]	input	Incoming connections from X2App modules
x2Out [ ]	output	Outgoing connections to X2App modules
x2GtpIn	input	Incoming connection from GtpUserX2 module
x2GtpOut	output	Outgoing connection to GtpUserX2 module
